Officers found two cannabis production factories in Oliver Street and Coniston Road. They also found drugs production equipment at one property in Pitt Street.

Their combined haul totalled 48 plants. One man has been arrested and enquiries are ongoing.

Details of the operation were revealed at a Police And Communities Together meeting in Mexborough last Thursday.

Inspector Ray Mountford said: “We got 32 plants from the address in Coniston and 16 from the one in Oliver Street. A drugs set up was also found in Pitt Street.

“Drugs offences blight communities. You very often get people coming and going from these properties at all times of the day. If you are bothered by this then please tell police.”

Insp Mountford warned police teams are working on further operations.

He said: “It’s difficult to put an exact amount on street value, but it will be in the thousands. Action may not be taken immediately because it takes time to gather evidence, but we will always take action in the end.

“We also did a leaflet drop in the area to let people know about what we are doing. It is important to let people know why so many officers have been in one particular area.”

Police arrested a 26-year-old man at Coniston Road on suspicion of cannabis production. Nobody was in at the Oliver Street raid and enquiries are ongoing.

Officers have arranged to interview a man in relation to drugs paraphernalia found at Pitt Street.
